Ocean of Life by Callum Roberts (Allen Lane)The judges said: 'This book invites you to imagine the unimaginable. It tells an extraordinary tale of scientific discovery and stands out by its ability to speak to people who are not scientists.'Observer reviewers Robin McKie wrote: 'In another writer's hands, Ocean of Life might have ended up as a mordant tale of ecological despair. Roberts, to his credit, gives us hope and provides a prescription for political and public action, right down to our choices of seafood in supermarkets.'Read an Observer interview with Callum Roberts here

It’s a bit like reading a novel, personal and compulsive!'Observer reviewer Sophie Scott wrote: 'He draws on both science and art to marvellous effect in his exploration of why early memories are so often filled with sunlight.'Read the full review here

The Book of Barely Imagined Beings by Caspar Henderson (Granta)The judges said: 'Henderson taps into forgotten wonder we first felt as children discovering the creatures of our world.

The book itself is a beautiful object and brings barely imagined beings to life.'Guardian reviewer Gavin Francis wrote: 'A spellbinding book that seeks to astonish us with the sheer intricacy, diversity and multiplicity of life forms that share our planet.'Read the full review here
